<br />archaeological and historical importance within the study area. There are <br /> <br />no known historical or archaeological sites that will be affected by salin- <br /> <br />ity control work. It is recognized, however, that the area has been occu- <br /> <br />pied at various times in the past and there is a good possibility that <br /> <br />artifacts may be discovered when working in previously undisturbed soils. <br /> <br />If cultural resources are discovered during construction the State <br /> <br />Historic Preservation Officer has agreed that to expedite both excavation <br /> <br />and evaluation of any finds, construction should be stopped for a maximum of <br /> <br />48 hours to provide opportunity for a qualified archaeologist to examine the <br /> <br />site, to advise the landowner as to potential eligibility for the National <br /> <br />List of Historic Places, and to decide upon potential mitigative or recovery <br /> <br />measures. If sites are found that are eligible for the National Register of <br /> <br />Historic Places the State Historic Preservation Officer, Interagency Archae- <br /> <br />ological Services and the Advisory Council on Historic Preservation will be <br /> <br />advised and given a reasonable opportunity to comment on the proposed acti- <br /> <br />vities or recovery plan in accordance with Soil Conservation Service proce- <br /> <br />dures for protecting archaeological and historic properties encountered in <br /> <br />SCS assisted programs (7 CFR 656, July 18, 1971, as amended July 23, 1978). <br /> <br />Climate <br /> <br />The mean annual temperature at Delta is 510F and ranges from a July <br /> <br />mean of 940F to a January mean of 140F. The mean annual temperature for all <br /> <br />Lower Gunnison stations is 49.60F. The average annual precipitation at <br /> <br />Delta is 8 inches and 9 inches at Montrose. About one half is in the form <br /> <br />of winter snow. The average length of the growing season is 146 days near <br /> <br />Delta with elevation of 4,960 msl and 152 days at Montrose, elevation 5,800. <br /> <br />The estimated length of growing season at Crawford and other locations at <br /> <br />higher elevations is about 105 days. The area below about 6,200 feet <br /> <br />elevation is characterized by low precipitation, low humidity, abundant <br /> <br />sunshine, and a wide range in annual and daily temperatures. <br /> <br />001222 <br /> <br />III-4 <br />
